/**
 * Get a `dt-tag td` node from a row, taking into account column visibility.
 * While getting a `dt-tag td` node is easy when it is visible on the page by
 * using normal DOM methods, jQuery or whatever, it becomes a lot more
 * complicated when taking into account hidden rows and columns. This function
 * can be used to overcome these difficulties.
 *
 * DataTables 1.10+'s new API provides the `dt-api cell()` and `dt-api cells()`
 * methods which are preferable for use over this method. As such this method is
 * marked deprecated, but is available for use with legacy version of
 * DataTables. Please use the new API if you are used DataTables 1.10 or newer.
 *
 *  @name fnGetTd
 *  @summary Get the `dt-tag td` element for a cell.
 *  @author [Allan Jardine](http://sprymedia.co.uk)
 *  @deprecated
 *
 *  @param {node} mTr `dt-tag tr` element to get the `dt-tag td` of
 *  @param {integer} iTd Column index to get the node of
 *  @param {boolean} bVisOnly Consider visible columns only
 *  @returns {node} `dt-tag td` element in question
 *
 *  @example
 *    $(document).ready(function() {
 *        var table = $('#example').dataTable();
 *         
 *        // Sort in the order that was origially in the HTML
 *        var nTd = table.fnGetTd( $('#example tbody tr:eq(1)')[0], 1 );
 *        console.log( nTd );
 *    } );
